Addition
Glass Solvent Addition Funnels Design permits addition of solvents to flash chromatography columns without disturbing the silica-gel / packing layer. • Lower end of the funnel is closed, and the stem has a series of small holes for solvent drainage • Funnel top is 75mm in diameter • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
Powder Addition Funnels with Vacuum Hose Connection and Standard Taper Joint These funnels are ideal for adding solids or liquids to reaction set-ups under vacuum conditions.
•
Applying a vacuum cuts filling time in half
• The funnels fit tubing ID ¼” and have a 60° side angle and a standard taper inner joint • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements

1-1/2” Stem Powder Addition Funnels • KIMAX® funnel with a short, wide stem • Constructed with a heavy uniform wall and a
Outer Baffled Short Stem Powder Addition Funnels • The exclusive KIMAX® 58° funnel promotes faster, more effective filtering because the cone is suspended by its uppermost edge • A piece of filter paper, when folded to form the
strong, fire-polished rim and stem to provide a long service life Funnel has a high resistance to chemical attack and mechanical and thermal shock Designed from ASTM Specification E1095, Type IV requirements
